WASHINGTON, D.C.—The National Nuclear Security Administration recently successfully recovered a disused, high-activity cesium-137 source from Massachusetts General Hospital in downtown Boston and transported it for permanent disposition. Formerly used as a research irradiator for medical studies, the device contained cesium-137, which could be used in a dirty bomb. The removal was part of NNSA’s global campaign to prevent terrorists from acquiring nuclear and radiological material.

“This operation is a key part of the NNSA’s broad strategy to strengthen both U.S. and global security by keeping dangerous nuclear and radiological material safe and secure,” said NNSA Deputy Administrator for Defense Nuclear Nonproliferation Anne Harrington. “Today’s announcement is a good example of how NNSA utilizes its unique expertise and assets at the national laboratories to partner with local communities and other agencies to make our cities and those around the world safer and more secure.” [Read more…]

WASHINGTON, D.C.—The National Nuclear Security Administration announced this week that it has recovered high-activity radioactive materials from an oncology clinic in Ciudad Juarez, Mexico.

NNSA’s Global Threat Reduction Initiative, or GTRI, and the Mexican National Commission for Nuclear Security and Safeguards, or CNSNS, jointly supported the removal, a press release said. The device containing the source was packaged and securely transported to the U.S. for final disposition.

“This operation is part of NNSA’s broad strategy to strengthen both U.S. and global security by keeping dangerous nuclear and radiological material safe and secure,” said NNSA Deputy Administrator for Defense Nuclear Nonproliferation Anne Harrington. “This mission is a good example of our long-standing partnership with Mexico to prevent proliferation and secure the materials that can be used by terrorists in an improvised nuclear device or dirty bomb.” [Read more…]

NNSA partners with Russia to recover ‘dirty bomb’ material

WASHINGTON, D.C.— The National Nuclear Security Administration, in partnership with the Russian Federation, has successfully completed the removal of 14 Russian radioisotope thermoelectric generators, or RTGs, from the Northern Sea Route. These devices, which contain high-activity radioactive sources, powered navigational beacons along Russia’s northern coastline. With this removal, the U.S. Department of Energy has completed its efforts to recover RTGs along the Northern Sea Route, a press release said.

RTGs were used for many years in Russia to generate electrical power at remote locations, including lighthouses and navigational beacons. The 14 RTGs recently recovered by DOE contain more than one million curies of strontium-90, a high-activity radioisotope that could be used in a dirty bomb. [Read more…]
